<p>Checking in from @rust-lang/compiler triage:</p>
<p>This seems to be related to our LLVM upgrade. The linked issue (<a href="https://github.com/rust-lang/rust/issues/63361" target="_blank" title="https://github.com/rust-lang/rust/issues/63361">#63361</a>) was blamed on LLVM bug 42935 and fixed by @nikic via a LLVM submodule update (<a href="https://github.com/rust-lang/rust/issues/63415" target="_blank" title="https://github.com/rust-lang/rust/issues/63415">#63415</a>).</p>
<p>cc @nikic and @nagisa -- Any thoughts on what's going on here?</p>

<p>Seems unfortunate. I feel like we're going to call this P-medium. Would be nice if we had a way to "kick it" to the LLVM wg for consideration, but I know that there's no process for that (and nobody I think with enough dedicated time to keep such a pipeline going).</p>
